* New wxStream classes: wxStreamBuffer and wxObject*Stream.

* Changes: ofsInvalid => wxInvalidOffset in filefn.h
* Updates: all wxStream classes use wxStreamBuffer.
           wxObject basic declaration changes (added LoadObject, modified
           StoreObject)
* Some base of the serialization.
(I hope not to have forgotten any files)
